Hydrogen Atom — 2D Bohr Model

A flat, top-down Bohr-model diagram of hydrogen: step the electron through energy levels n=1–5 using the real Bohr radius, velocity and energy formulas, and compare the protium, deuterium and tritium isotopes.

This 2D companion redraws the same Bohr-model physics as the 3D version as a flat, top-down diagram: pick an isotope, then move the energy-level slider (n=1–5) to watch the electron jump to the radius, speed and binding energy the Bohr formulas predict for that level, with prior orbits shown as faint rings for comparison.

⚙ Under the hood

Canvas 2D Bohr-model diagram driven by the real hydrogen formulas r_n=n²a₀, v_n=v₁/n and E_n=-13.6/n² eV, with isotope, orbit-speed and view-tilt controls.
